A team of astronomers says that observations with the National Science Foundation’s Very Large Array radio telescope show that a neighboring bloated star has giant convective plumes propelling gas from its surface up into the star’s atmosphere.
A team of astronomers using a pair of National Science Foundation radio telescopes has made the first measurements of the size and expansion of a mysterious, intense fireball resulting from a cosmic gamma ray burst last May.
Marking an important new milestone in radio astronomy history, scientists at the National Radio Astronomy Observatory in Socorro, New Mexico, have made the first images using a radio telescope antenna in space.
Radio astronomers revealed that the first gamma-ray burster ever detected at radio wavelengths has surprised them by its erratic behavior.
New observations with the National Science Foundation’s Very Long Baseline Array indicate that the inner workings of active galaxies may be considerably more complex than astronomers have previously thought.
Astronomers at the National Radio Astronomy Observatory have used the continent-wide Very Long Baseline Array to map for the first time the magnetic field on the surface of a star other than the Sun.
Astronomers have used the National Science Foundation’s Very Large Array radio telescope to make the first detection of radio emission from a cosmic gamma-ray burst.
A claim that the universe has a preferred direction is not supported by recent observational evidence, according to three astronomers who analyzed data from the Very Large Array radio telescope in New Mexico and the WM Keck Telescope in Hawaii.
The launch of a Japanese satellite will help create the largest astronomical instrument ever built — a radio telescope more than two-and-a-half times the diameter of the Earth.
The discovery of microquasars within our own Milky Way Galaxy has won two astronomers a prize from the High Energy Astrophysics Division of the American Astronomical Society.
